Gas-chromatographic speciation of methylstannanes in the Chesapeake Bay using purge and trap sampling with a tin-selective detector

A purge and trap sampler, which collects and concentrates volatile organotins from water samples has been developed. The sampler is coupled automatically to a gas chromatograph equipped with a commercial flame photometric detector, modified for tin-specific detection by use of an interference filter...

Summary:A purge and trap sampler, which collects and concentrates volatile organotins from water samples has been developed. The sampler is coupled automatically to a gas chromatograph equipped with a commercial flame photometric detector, modified for tin-specific detection by use of an interference filter. The method allows non-destructive speciation and detection of both hydrophilic and hydrophobic organo-tin species in aqueous systems and has been used to analyse water samples from Chesapeake Bay and Baltimore harbour, where several methyltin compounds, including methylstannanes, were detected.
